Specification of Letters Patent.

- Patented Sept. 21, 31915.

Application filed June 13, 1913; serial No. 773,418.

To all whom it may concern."

Be it known that I, KARL ELLINGEN, a subject of the Emperor of Germany,residing at Farristrasse No. 62, Bochuni, Germany, have invented certainnew and useful Improvements in Coke-Ovens, of which the following is aspecification. v V

This invention relates to coke-ovens, and

more especially to that type comprising horizontal coking chambershaving side are arranged. The object is to provide a simple, practicaland advantageous construction and arrangement whereby two kinds of fuelgases "can be used, either independently or in combination and-invariable proportions. The

gases Whiclritis thus proposed tomake use of arezgas 'ofrelatively 10Wcalorific value,

such as producer gas or gas from a shaft furnace, and gas of'relativelyhigh calorific value, such as gas from the charge that isbeing coked inthe coke-oven. Fuel gas of the first kind, it may be stated, requirespreheating, whereas the gas coming from a coke-oven requires nopreheating. I

The invention resides more particularly in a construction wherein theheating flue may be supplied from a passage for heating gas of lowcalorific value, or from a tubular member constituting a conduit for gasof higher calorific value, such as coke-oven gas, being adjustable somission of low calorific gas and being itself provided with valve meansfor controlling the amount of high calorific gas supplied. Thus the ovencan be operated with 10W calorific gas alone, with high calorific gasalone, or with a combination of both, and in any case the amount ofeither or both of the gases is variable at will. It is evident that withan organization of this'character exact and complete control isobtainable, While at the same time a dual fuel supply is made available.

The accompanying drawings illustrate a preferred mode of carrying theinvention into effect, and the essentials thereof will be found pointedout more particularly in the appended claims.

lathe said drawings; Figure 1 is a vertical transverse section through aportion of a coke-oven structure; and Fig. 2 is a vertical section, onan enlarged scale, through the means for supplying the high calorificgas, "which means constitutes also a valve mechanism for regulating theflow of the low calorific gas.

It will be understood that the illustration is only fragmentary and toan extent diagrammatic.

The horizontal coking chambers are indicated at a. As is customary,these are provided with side heating Walls 'Z ,,in which are formedvertical heating flues c, which may extend throughout the length of thecoking chambers or be subdivided into groups of fines in any desired orcustomary manner. The outlets from these fines have not beenspecifically illustrated, because they may be ot'any appropriatecharacter .as far as the present invention is concerned. Below thecoking chambers in the foundations of thc structure there are tunnels25. These are preferably located beneath every other coking chamber, sothat the apparatus in each tunnel serves the heating fines of two sideheating walls.

Means are provided for supplying each heating flue c with air forcombustionand fuel gas of one kind. Preferably both of these suppliesmnnnunicate with the heating sage f and a longitudinally-extendingairpassage h at opposite sides of the lower portion of each combustionfine, and beneath the latter there is a longitudinally-extending fuelgas channel 6, which channel communicates with the corresponding line bymeans of a series of nozzle openings or t-Wyers'd. The air passages 71communicate With the lower part of the combustion flue by'later-alopenings i, while the-fuel gas passage f communicates with the gaschannel 6 ,by lateral openings g. it Wlll be understood that the numberand spacing of the openlugs 71 and y will be determined by theparticular conditions of different cases, and,

similarly, the number and size of the tvvyer openings (1? may be varied..The gas passages 7 supply the combustion fines with fuel,

gas of low calorific value and area ccordingly provided with appropriateconnections (not shown) with the'usual regenerators, which, as will beunderstood lay-those skilled in the art, are alternately traversed bythe products of combustion and the gas to be preheated.

The invention contemplates supplying coke-oven gas, that is to say gasof the kind that comes from the coking chamber and which is of highcalorific value, to the same gas channels a which extend longitudinallybeneath the heating flues c, which channels may thus serve as mixingchambers where the two kinds of fuel gas are mingled before entering thecombustion flue. The means for admitting this gas of high calorificvalue constitutes also a 'valve mechanism for regulating or cutting offthe flow of the; low calorific gas from the passage f. Furthermore, thisvalve mechanism, as well as the means for controlling the flow of thehigh calorific gas, are operable from the tunnel t.

' Thus, a series of vertical openings or shafts 8 extend upward throughthe masonry from the tunnel t to each channel 6, and in these openingsare tubular members 39 which are provided at their upper ends withhollow These latter are prefervalve portions k. ably of refractory stoneor other suitable heat-resisting material, and are mountedon the hollowstems 7) infany" suitable manner. It will be understood that there isone of these valve members 71, k for each of the twyer openings (hthevalve member being disposed vertically beneath the latter so that byvertical adjustment each valve member controls the effectivecross-section of the corresponding opening. By moving the valve membersupward to the limit they completely close the twyer openings to passageof low calorific gas from the ducts f. At such time, however, or, ifdesired, when the valve members are adjusted to permit admission 'ofmore or less gas from thepassages f, gas of high calorific power, suchas coke-oven gas, may be supplied through the valve members themselvesand through the openings 0? into the combustion flues. In the preferredconstruction there is a longitudinal gas main n, suitably supportcdby a'or effecting variatiop of such adjustment.

In the illustrative construction shown the stems 19 passslidablythr'ough removable sockets to mounted on suitable supports :27 I

and havingset" screws 2 for engagement, with said stems. By looseningthese screws the stems 19 may be raised and low ered, so as to effectcorresponding adjustment of the valve members k, and thereafter the setscrews are tightened to hold the-i-idesages 1. By opening. the valves 1the combustion .flues will obviously be suppliedwith apparent that byadjusting the valve members 70 to the desired height and by regulatingthe degree of opening of the valves Z the proportions and amounts of thetwo kinds of gases may be exactly regulated. If the valve members is aremoved up as far as they will go and valves Z are opened; the combustionflues will be supplied with fuel gas only from the main 12.. When bothkinds of fuel gasare being utilized simultaneously it will be observedthat they are mingled in the channels 6 and twyer openings d beforeentering the combustion flue. Under such conditions the tubular members"la. act as nozzles delivering their jets of high calorific gas into thechannels e in line with the openings d, with a consequent entraining oraspirating action on the low calorific gas in the channel.
